Claude Haiku 4.5
Vendor keyClaude Haiku 4.5 is the fastest model in Anthropic's current lineup, with near-frontier intelligence. It uses manual extended thinking rather than the adaptive thinking of the larger current models, and does not support the effort parameter. The ID claude-haiku-4-5 is an alias that resolves to this pinned snapshot.
